Areal Average Albedo VAP Evaluation Data Now Available
Nov 02, 2015       
A new value-added product (VAP) estimating the surface albedo at Multifilter Rotating Shadowband Radiometer (MFRSR) spectral wavelengths is now available from the Southern Great Plains (SGP). The Areal Average Albedo (AREALAVEALB) VAP data set is unique in that it gives an estimate of the average albedo for the relevant area around a site. Traditionally albedo [...]

Surface Meteorological Data Overhaul Completed
Aug 28, 2015       
In an effort to provide data product consistency, the task of reprocessing historical surface meteorology data was recently completed. As the ARM Climate Research Facility grew both in size and scope, it became important to create homogenous data sets to ease navigation for users, while providing a straightforward approach for ARM infrastructure staff to maintain [...]

Doppler Lidar Profile VAPs Now Available
Aug 27, 2015       
The ARM Facility currently operates several scanning coherent Doppler lidar systems at various sites around the globe. These instruments operate in the near infrared and provide measurements of radial velocity, attenuated aerosol backscatter, and signal-to-noise ratio. Previously shared with the ARM user community as an evaluation product, these data are now in production and available [...]

AmeriFlux and Methane Evaluation VAP Now Available for Barrow Data
Apr 21, 2015       
Greenhouse gases (GHGs) are suspected to be key drivers of global climate change. As Arctic permafrost melts, it unlocks stored carbon, which may contribute to large increases in the atmospheric mixing ratios of these gases. Understanding the rates and controlling mechanisms of these releases is of great importance for climate prediction and modeling. The ARM Climate [...]
